I have my sons 3.3 tmaxx, used to run good when I got it for him back in March/April. Bought it used, but ran good. Then the temperature went up outside and the humidity. Factory settings are LSN flush, HSN out 4 turns, it starts fine, take ignitor off, hit throttle and go 2-3 feet and die. I was messing with the LSN, leaning it truck went about 20-25 foot then died. I would like to get it tuned, but dont want to go too lean. I am thinking the issue is with the LSN, not the HSN, can do the HSN later. any ideas or suggestions you might have? I live in Indiana if that makes any difference for altitude.
